In this process moulds are made of silicon rubber material. The process involves making of the master pattern using any available rapid prototyping techniques. This pattern is then finished to the quality in which final parts are required.
In this process moulds are made of silicon rubber material. The process involves making of the master pattern using any available rapid prototyping techniques. This pattern is then finished to the quality in which final parts are required. It is then suspended in an enclosed box and liquid silicone rubber is poured all around it. This sets with time and becomes a solid rubbery mass with the pattern inside. Now the mould is cut along its parting line and the pattern is removed from within.
These are primarily used to create multiple prototypes. Rapid prototyping techniques are not economical when more than one prototype needs to built for the same component. In these cases different rapid tooling techniques have been developed to manufacture 25-30 prototypes, few hundred to a few thousand prototypes and prototypes in excess of 50000 pieces.
